路径切换方法、控制器、节点以及存储介质
相关申请的交叉引用
本申请基于申请号为202110728329.X、申请日为2021年6月29日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请实施例涉及但不限于通信领域，尤其涉及一种路径切换方法、控制器、节点以及存储介质。
背景技术
目前的5G技术相对于以往的技术，最大的特点是业务具有很强的动态性，对于分段路由(segment routing，简称SR)隧道来讲，网络长期运行之后，网络会变得异常复杂(如重路由，扩缩容等)，链路流量出现大量不均衡等情况，大量业务不在最优路径上，为了保障业务能够维持在一个最优的路径上，需要对隧道进行隧道重优化处理。现有的隧道重优化处理主要采用移动宽带(mobile boardband,简称MBB)技术，但多协议标签交换(Multi-Protocol Label Switching，简称MPLS)隧道存在许多中间节点，MBB主要用于在所有的节点实现MPLS隧道迁移，对于网络的拓扑结构要求比较高且经过的所有节点要支持同一流程，而且为了保证路径上的所有节点的隧道都全部重优化完，再切换到新的隧道上，往往会出现延时的问题，加大了配置时间，并且随着网络的规模和复杂度不一样，难以将延时时间设置到最优状态，从而造成业务损伤。
发明内容
以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
本申请实施例提出一种路径切换方法、控制器、节点以及存储介质，能够至少在一定程度上快速修改业务报文的路径信息，在修改过程中不会影响现有的业务报文传输。

具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本申请进行进一步详细说明。应当理解，此处所描述的具体实施例仅用以解释本申请，并不用于限定本申请。
需要说明的是，虽然在装置示意图中进行了功能模块划分，在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于装置中的模块划分，或流程图中的顺序执行所示出或描述的步骤。说明书、权利要求书或上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
本申请实施例提供了一种路径切换方法、控制器、节点以及存储介质，该路径切换方法包括但不限于如下步骤：在业务报文通过第一路径进行转发的情况下，获取切换路径信息，其中，第一路径根据第一数据页的第一路径信息所配置得到，根据切换路径信息将第二数据页的第二路径信息向业务报文进行配置，以使业务报文从第一路径切换至第二路径进行转发。在本技术方案的实施例中，业务报文在根据第一数据页的第一路径信息所配置得到的第一路径中进行转发的过程中，获取表征将业务报文从第一路径切换至第二路径的切换路径信息时，可以根据该切换路径信息将第二数据页的第二路径信息向业务报文进行配置，从而能够将业务报文从第一路径直接切换至第二路径进行转发，因为从第一路径快速切换至第二路径的过程中以数据页进行切换，能够快速修改业务报文的路径信息，在修改过程中不会影响现有的业务报文传输。
下面结合附图，对本申请实施例作进一步阐述。
系统架构平台设置有多种节点，每种节点分别具有对应的功能，不同节点相互协同来实现业务链的整体功能。
系统架构平台可以包括多种节点，每种节点分别具有对应的功能，不同节点相互协同来实现业务链的整体功能。通常情况下，多种节点可以包括管控系统、设置在核心层的网络侧边缘路由器(network provider edge，简称NPE)、设置在汇聚层的运营商侧边缘路由器(service provider-end edge，简称SPE)以及设置在接入层的用户侧边缘路由器(user provider-end edge，简称UPE)等。
例如，参见图1，图1是本申请实施例提供的一种用于执行路径切换方法的系统架构平台的示意图。在图1中，NPE节点为NPE节点1、NPE节点2，SPE节点为SPE节点1、SPE节点2，UPE节点为UPE节点1、UPE节点2、UPE节点3、UPE节点4、UPE节点5、UPE节点6、UPE节点7、UPE节点8、UPE节点9、UPE节点10、UPE节点11。管控系统用于分别与SPE节点1、SPE节点2连接。图1中的系统架构平台可以应用在切片分组网中(Slicing Packet Network，简称SPN)。
参见图2，SPE节点用于对业务报文进行业务处理。通常来讲，SPE节点可以和一个或多个UPE节点连接。SPE节点可以包括接收模块、配置模块和数据页，其中，接收模块用于接收来自控制系统的路径信息，配置模块可以用于新建或者删除数据页，还可以用于将接收模块所获取的路径信息配置在数据页上。
需要说明的是，当数据页有多个的时候，说明书中以第一数据页、第二业数据、第三数据页或者第N数据页进行区分。
需要说明的是，每一个数据页的字节数可以相同，可以不相同，本实施例对数据页的字节数不作具体限定。
图1所示的管控系统可以是服务器、主机、个人计算机、SPE节点或者终端设备。SPE节点用于根据管控系统的路径信息，将接收到的业务报文转发至UPE节点。SPE节点可以是路由器、交换机或者其他SPE节点，本实施例对其不作具体限定。UPE节点可以是路由器或者其他SPE节点，本实施李对其不作具体限定。
SPE节点以及UPE节点可以作为数据面。在一个实施例中，SPE节点和UPE节点可以建立隧道，SPE节点和UPE节点之间可以通过隧道来传输报文。其中，该隧道可以是虚拟扩展局域网(英文：Virtual Extensible Local Area Network，简称：VXLAN)、通用路由封装(英文：generic routing encapsulation，简称：GRE)隧道(tunnel)、移动IP数据封装和隧道(英文：IP-in-IP)等。
数据面可以通过控制面来控制。控制面可以包括一个或多个管控系统。例如，在一个实施例中，在报文传输之前，客户端可以将业务的属性信息发送至管控系统，管控系统可以根据客户端发送的业务的属性信息以及数据面的拓扑，计算得到路径信息，然后将路径信息发送至SPE节点，从而通过SPE节点对业务进行隧道的路径配置处理，得到配置后的业务报文。
应理解，图1所示的系统架构平台中各个节点的类型为可选方式，本申请实施例中系统架构平台中节点的类型可以比图1所示的更多，此时系统架构平台还可以包括其他类型的节点；或者，系统架构平台中节点的类型也可以比图1所示的更少，本申请实施例对SFC的系统架构中节点的类型不做限定。
应理解，图1所示的系统架构平台中各个节点的数量为可选方式，本申请实施例中系统架构平台中节点的数量可以比图1所示的更多，或者比图1所示的更少，例如，上述SPE节点可以仅为一个，或者上述UPE节点为几十个或几百个，或者更多数量；又如，上述UPE节点为几十个或几百个，或者更多数量，本申请实施例对系统架构平台中节点的数量不做限定。
本领域技术人员可以理解的是，该系统架构平台110可以应用于通信网络系统以及后续演进的移动通信网络系统等，本实施例对此并不作具体限定。
本领域技术人员可以理解的是，图1中示出的系统架构平台并不构成对本申请实施例的限定，可以包括比图示更多或更少的部件，或者组合某些部件，或者不同的部件布置。
基于上述系统架构平台，下面提出本申请的路径切换方法的各个实施例。
如图3所示，图3是本申请一个实施例提供的路径切换方法的流程图，该路径切换方法应用于SPE节点，并且该路径切换方法包括但不限于有步骤S100、步骤S200。
步骤S100，在业务报文通过第一路径进行转发的情况下，获取切换路径信息，其中，第一路径根据第一数据页的第一路径信息所配置得到。
具体地，在业务报文通过由第一数据页的第一路径信息所配置得到第一路径进行转发的情况下，如果管理系统计算得到一条传输性能相比于第一路径的传输性能更优的第二路径时，会向SPE节点发送切换路径信息，以要求SPE节点对业务报文配置传输性能更优的第二路径的第二路径信息。
需要说明的是，传输性能可以根据路径经过的节点数量、每个节点传输的时延情况、每个节点传输速率以及每个节点的负荷情况等指标得到，本实施例对其不作具体限定，可以根据实际数据面的网络情况进行设置。
需要说明的是，切换路径信息可以表征在第一路径的传输性能下降的情况下，要求SPE节点将业务报文从第一路径切换至第二路径；也可以表征管理系统计算得到一条传输性能相比于第一路径的传输性能更优的第二路径，要求SPE节点将第二数据页中的路径信息更新为第二路径信息，再将业务报文从第一路径切换至第二路径，本实施例中的切换路径信息根据场景不同表征不同的路径切换要求。
需要说明得是，切换路径可以是切换SPE节点的输出端口，可以是切换首节点与目标节点之间的路由，本实施例对于切换路径的不作具体限定。
步骤S200，根据切换路径信息将第二数据页的第二路径信息向业务报文进行配置，以使业务报文从第一路径切换至第二路径进行转发。
具体地，当SPE节点接收到切换路径信息时，可以根据切换路径信息将第二数据页的第二路径信息向业务报文进行配置，从而能够将业务报文从第一路径直接切换至第二路径进行转发。因为在切换之前，业务报文仍然按照第一路径转发，所以配置第二路径信息的时候不会引起业务变化，切换分页的时候，所有的数据都已经更新完成了，所以也不会引起任何的隧道告警等情况，业务也不会受损，能够保证网络的健壮性及连续性。
在一实施例中，在业务报文通过由第一数据页的第一路径信息所配置得到第一路径进行转发的情况下，如果管理系统计算得到一条传输性能相比于第一路径的传输性能更优的第二路径时，会向SPE节点发送切换路径信息，当SPE节点接收到切换路径信息时，可以根据切换路径信息在第二数据页中进行更新配置第二路径信息，再将第二数据页的第二路径信息向 业务报文进行配置，从而能够将业务报文从第一路径直接切换至第二路径进行转发，因为从第一路径快速切换至第二路径的过程中以数据页进行切换，能够快速修改业务报文的路径信息，在修改过程中不会影响现有的业务报文传输。
在一实施例中，在业务报文通过由第一数据页的第一路径信息所配置得到第一路径进行转发的情况下，如果管理系统计算发现第一路径的传输性能变下降到比第二路径更低时，会向SPE节点发送切换路径信息，当SPE节点接收到切换路径信息时，可以根据切换路径信息将预先配置的第二数据页的第二路径信息向业务报文进行配置，从而能够将业务报文从第一路径直接切换至第二路径进行转发，因为从第一路径快速切换至第二路径的过程中以数据页进行切换，能够快速修改业务报文的路径信息，在修改过程中不会影响现有的业务报文传输。
在一实施例中，基于图1和图2，在业务报文通过由第一数据页的第一路径信息所配置得到第一路径并以SR隧道的方式进行转发的情况下，其中第一路径为SPE1-UPE1-UPE2-UPE3，管控系统进行隧道重优化处理，变更业务报文的隧道转发路径，即将业务报文的隧道转发路径从第一路径变更为第二路径，管控系统可以将新的路径配置下发到首节点SPE1的接收模块，接收模块接收到第二路径的配置数据(即第二路径信息)之后，将第二路径的配置数据转发给配置模块，配置模块直接将第二路径的配置数据配置到非业务转发页(即第二数据页)中，如当前业务报文在第一数据页上转发，则更新为第二数据页，否则更新第一数据页；第二数据页更新完成之后，SPE节点1的隧道转发路径从第一路径变更为第二路径，其中第二路径为SPE1-UPE1-UPE8-UPE7-UPE6-UPE5-UPE4-UPE3，因为在切换之前，业务报文仍然按照第一路径转发，所以配置第二路径信息的时候不会引起业务变化，切换分页的时候，所有的数据都已经更新完成了，所以也不会引起任何的隧道告警等情况，业务也不会受损，能够保证网络的健壮性及连续性。
参照图4，本申请一个实施例提供的路径切换方法还包括但不限于步骤S410和步骤S420。
步骤S410，获取第二路径信息；
步骤S420，根据第二路径信息在第二数据页中进行配置，得到第二数据页的第二路径信息。
在一实施例中，在SPE节点接收到切换路径信息，该切换路径信息表征管理系统计算得到一条传输性能相比于第一路径的传输性能更优的第二路径，要求SPE节点将第二数据页中的路径信息更新为第二路径信息，再将业务报文从第一路径切换至第二路径时，SPE节点可以从管理系统中获取到第二路径信息，根据第二路径信息更新第二数据页中的路径信息为第二路径信息，得到第二数据页的第二路径信息，即在业务报文切换路径之前，SPE已经配置好第二数据页的第二路径信息。
在一实施例中，在SPE节点开始对业务报文进行路径配置之前，SPE节点会接收到第一路径信息和第二路径信息，那么此时SPE节点可以根据第一路径信息和第二路径信息新建第一数据页和第二数据页，将第一路径信息配置在第一数据页中得到第一数据页的第一路径信息，将第二路径信息配置在第二数据页中得到第二数据页的第二路径信息，即在业务报文通过SPE节点进行转发前，SPE已经配置好第一数据页的第一路径信息和第二数据页的第二路径信息。
参照图5，步骤S420之后还包括但不限于步骤S510。
步骤S510，根据第二路径信息在第二数据页中进行重新配置，并对已配置第二路径信息的第二数据页中的数据进行校验处理。
具体地，在第二数据页中已完成配置第二路径信息之后，可以将第二路径信息在第二数据页中进行重新配置，由于第二数据页已经通过步骤S420进行配置，两次配置之间数据没有变化，不会引起任何业务损伤，同时步骤S510还会对已配置在第二数据页中的数据进行校验，可以确保第二数据页中的数据完全正确。
参照图6，步骤S200之后还包括但不限于步骤S610和步骤S620。
步骤S610，获取用于向业务报文配置第三路径的第三路径信息，第三路径的传输性能比第一路径的传输性能更优；
步骤S620，将第一数据页中的第一路径信息更新为第三路径信息。
具体地，当业务报文从第一路径通过数据页切换技术切换至第二路径进行转发的过程中，从管理系统获取到用于向业务报文配置第三路径的第三路径信息，该第三路径的传输性能比第一路径的传输性能更优，那么此时可以将第一数据页中的第一路径信息更新为第三路径信息，后续可以根据第二路径的传输性能情况，再决策是否需要切换至第三路径进行转发，以使业务报文能够保持在最优路径中传输。
参照图7，步骤S200之后还包括但不限于步骤S710。
步骤S710，当接收到来自第二路径的告警信息，将第一数据页的第一路径信息向业务报文进行配置，以使业务报文从第二路径切换至第一路径进行转发。
具体地，当接收到来自第二路径的告警信息，则表示第二路径出现故障，此时不能再使用第二路径对业务报文进行转发了，那么可以将切换前的第一数据页的第一路径信息向业务报文进行配置，以使业务报文从第二路径切换至第一路径进行转发，即当切换到第二数据页之后，如果业务报文转发过程出现异常或者业务报文出现大量损伤等情况，通过检测第二路径告警机制，将第二路径重新切回到第一数据页的第一路径中进行转发，保证业务连续性。
需要说明的是，该告警信息来自操作维护管理(Operation Administration and Maintenance，OAM)信息，OAM信息是指根据运营商网络运营的实际需要，通常将网络的管理工作划分为3大类：操作(Operation)、管理(Administration)、维护(Maintenance)，简称OAM。操作主要完成日常网络和业务进行的分析、预测、规划和配置工作；维护主要是对网络及其业务的测试和故障管理等进行的日常操作活动。
以太网OAM是一种监控网络故障的工具，主要用于解决以太网接入“最后一公里”中常见的链路问题。用户通过在两个点到点连接的设备上启用以太网OAM功能，可以监控这两台设备之间的链路状态。
以太网OAM能够有效提高以太网的管理和维护能力，保障网络的稳定运行，其主要功能包括：
链路性能监测：对链路的各种性能进行监测，包括对丢包、时延和抖动等的衡量，以及对各类流量的统计。
故障侦测和告警：通过发送检测报文来探测链路的连通性，当链路出现故障时及时通知网络管理员。
环路测试：通过非以太网OAM协议报文的环回来检测链路故障。
参照图8，步骤S710之后还包括但不限于步骤S810、步骤S820以及步骤S830。
步骤S810，删除第二数据页，并新建第三数据页；
步骤S820，获取用于向业务报文配置第四路径的第四路径信息，第四路径与第二路径不同；
步骤S830，根据第四路径信息在第三数据页中进行配置，得到第三数据页的第四路径信息。
具体地，在第二数据页出现故障问题并完成将业务报文切换至第一路径进行转发之后，如果管理系统计算得到比第二路径的传输性能更优的第四路径时，SPE节点可以删除第二数据页，并新建第三数据页，然后向管理系统获取用于向业务报文配置第四路径的第四路径信息，接着根据第四路径信息在第三数据页中进行配置，得到第三数据页的第四路径信息，后续可以根据第一路径的传输性能情况，再决策是否需要切换至第四路径进行转发，以使业务报文能够保持在最优路径中传输。
参照图9，步骤S710之后还包括但不限于步骤S910以及步骤S920。
步骤S910，删除第二数据页，并新建第三数据页；
步骤S920，将第二路径信息在第三数据页中进行配置。
具体地，在第二数据页出现故障问题并完成将业务报文切换至第一路径进行转发之后，如果管理系统没有计算得到比第二路径的传输性能更优的其他路径时，SPE节点可以删除第二数据页，并新建第三数据页，然后直接将第二路径信息在第三数据页中进行配置，得到第三数据页的第二路径信息，后续可以根据第一路径的传输性能情况，再决策是否需要切换至第二路径进行转发，以使业务报文能够保持在最优路径中传输。
参照图10，在步骤S100之前，包括但不限于步骤S1010、步骤S1020和步骤S1030。
步骤S1010，获取第一路径信息；
步骤S1020，根据第一路径信息在第一数据页中进行配置，得到第一数据页的第一路径信息；
步骤S1030，根据第一数据页的第一路径信息向业务报文进行配置，以使业务报文通过第一路径进行转发。
具体地，当管理系统接收到待转发的业务报文的属性信息，可以根据属性信息和当前的网络各个节点拓扑，计算得到两个以上符合业务报文的属性信息的路径，然后获取两个以上的路径的当前的传输性能，根据当前的传输性能确定第一路径和第二路径，第一路径为当前的传输性能中最优的路径，第二路径为当前的传输性能中次最优的路径，管理系统可以决策优先通过第一路径对报文进行转发，第二路径作为备用路径，第二路径用于当第一路径出现问题的情况下能够使业务报文快速切换至第二路径进行转发，那么此时，SPE节点可以获取第一路径信息，然后根据第一路径信息在第一数据页中进行配置，得到第一数据页的第一路径信息，再根据第一数据页的第一路径信息向业务报文进行配置，以使业务报文通过第一路径进行转发，能够使得业务报文从最优路径上进行转发。
